SamyGO

Hi, my TV UE55H6470 MST14DEUC has a reboot loop since a few days. After about 1 minute the TV restarts. Until then I can do everything. I have 2130 installed and rooted.
I found out that it works flawlessly when I unpluck the network cable but as soon as network connection is there (LAN or WIFI) the reboot loop is there.
I already tried factory reset, go back to 0000 and to 2130 again and I tried to block the common domains in the router but no success. I recorded network traffic and see a lot of packets coming from the TV right before it restarts but I have no idea how to maybe analyse the packets with wireshark or something.
How can I find out the root cause for that? Would maybe FW 2600 help or even later?

Today I found out, that blocking the whole internet connection in the router for the TV also doesn't help. So if internet is there or not doesn't matter. Its just that it has connection to a router?
Would be good to know how to debug in samygo or what is going on.
